' ment. These pipes form storage reservoirs for compressed air, from which the 'This mast has a Worm gear 3 crew and engines may be supplied. Directly beneath the turret there is a diving tank K', having a loner cover L opening outwardly, said correr being the full size of the tank. This cover has chains N' attached to its edges, which chains extend into pipes O. Drawrods Q' are attached tothe ends ol the chains, clamping handles R' are attached to these draw-rods. The handles rest on. brackets l" and hold the cover L firmly closed when deaired. The inner cover S of the diving tank may be clamped by screWsU', as many as may be needed. Water-tight joints will be seeuredby means of interposed gaskets. An air pipe, l/V, leads from. the compressed air reservoirs to the upper part of tank K'. This pipe W is controlled 'by a cock ZI', through which compressed airis admitted to the tank E. By closing cock Z and opening cock Xi', air can escape from tank K', through pipes W tothe interiorof the boat. A passage in cover L, at L", permits the ingress or egress of Water. `Wheu it is desired to sink the boat by means of the diving tank, theiair from said tank is allowed to escape by opening cock X, and Water will enter tank l thus changing the specific gravity ot' the boat as a whole. By closing cock X and opening cock 2l', compressed air from the reservoirs is altowed to enter thetauk, and drive out the water, restoring the buoyancy of the boat. The diving tank is placed exactly under the center of displacement, so that the trim of the boatehall not be altered. The outer cover opening outwardly, and the inner cover opening inwardly, form an air lock of the diving tank, through which a torpedo may be passed from the boat, or a diver may pass ont, provision being made, se by a passage at Sx, for the passage of a wire 'to the torpedo or an air hose to the diver. The diving tank K is a cylinder, placed in the center of compensating chamber or compartment ll'. Water is admitted to compartment ll' to compensate for the consumption of air and fuel. This` compartment should have a check valve opening outwardly. lWater ballast may be admitted to the compartments C2, around the pipes B2, A hollow rod,like a mast, 1,(Fig.3,) may be hinged to the'- shell abatt the turret. with which worm id worm being operated by at, The worm wheel enc ries :ses to turn the wheei. t en gages, se

mast up or down. Ahollow shaft 4 eominunh cateswiththe mast,and with apipeextending into the boat. An air pump connected with 7o this pipe may draw air into the boat when the mast extends above water. 'lhe float O may have a groove therein, so as to straddle the mast. "A gun, preferably a pneumatic gun 74 may be placed forward of the turret, extend- 75 ing parallel with theaxis of the boat. rlhe muzzle of this gun can be covered by a sliding shutter S, operated by pitman t) and bellcrank lcvcr 10, to open or close the muzzle. 'lhe muzzle ot this gun may be elevated by Se sinking the stern of thcboat, so that the (iight of the projectile will be mainly above water. The anchor l5 may be drawn into pipe or Well 1G, entirely within the beat. A windlass 17 having; shaft 19 extending through stulf- S5 -ing box 20, serves to wind up theanchor and a dog 2l engaging ratchet l2 locks the same. (See Figs. i3 and 7.)

For cutting a torpedo or telegraph cable, the hooked cutter 34: is provided, a blade 35 9o being in line therewith at the bottom of the boat. The cutter St is at the ond of a piston rod 32 passing through stuling box 33. Rod 32 has apiston head inside cylinder 30, and compressed air may be admitted to either end of said cylinder head 3l by a space 38. The hooked cutter may be thrust out and drag on the bottom until it picks up a cable, when it, may be drawn in by a pressure on thc piston rope or chain,

The inventor expects to cover modifications and equivalents within the scope of his invention. Air under extreme compression is stored in the pipes il?. 'lhis air is gradually liberated, to maintain a for breathing, and may also drive the engines by direct pressure or be used to support combustion. A checkyalve will permit the escape of air should the internal pressure be' come too great. iioat with the turret just'above water. when at rest. I Thus by means otdiving rudders or Wings, the boat may be driven under the' surface as soon as she has suliicient speed, or by shell of said turret, a camera-obscura sliding r 25 through-the ball, anda spring cover the ball, as set forth.

6. The roof of a. torpedo boat having an oritice therein, a stopper valve for said orifice, 'and a iloat connected to the 'valve substantially. as described, whereby the valve is opened when thefloat drops, and is closed when the ioat is lifted by the water.

7. In combination with the shell of a torpedo boat, a reel attached to said shell, a handie within the boat. whereby the reel is oper- `ated, a float and hose connecting said float faith thereel, and a pipe connection from the interior of the boat to the hose on the reel, substantially as described.
